First place gets $20,000 USD. Pretty good money for a weekend of work
Of course the skater only gets around half after taxes. I remember in Brennan's book that Frank or Michelle commented that they take both US and international tax from those winnings. Once you pay coach's fees to attend the event (usually coaches ask for money to make up for lost home lessons) and all the other stuff for training, you might as well stay home and not spend all that money for a chance to win 20K (which may wind up 11K after taxes).
